I've played through the beginning of Arkane Studio's Dishonored at least a half-dozen times, each time dreading the moment the killers make their move. Launching worldwide on April 16, Dishonored's second helping of downloadable content puts the assassin's dagger in players' hands. Can The Knife of Dunwall be redeemed?

It's chilling, seeing Corvo and the Empress from that angle and knowing what comes next, isn't it? That tragic event launches the master assassin Daud on a quest for redemption. The mysterious Outsider is an equal-opportunity enhancer, granting fresh new powers to this anti-hero to aid him on his journey. He'll track down Bone Charms and Runes with his Void Gaze, while learning to use deadly variations of Corvo's abilities.

Along with a little black magic, Daud will be able to summon his assassin brethren, daze enemies with Chokedust and Stun Mines, and launch a wide variety of darts from his concealed Wristbow.

Along with fresh locations like the Legal District and the whale carcass-studded Rothwild Slaughterhouse, Duad's journey will also grant players fresh perspective on key events from the main game.

More than just a simple side-story, The Knife of Dunwall is only the beginning of a larger tale, introducing players to a mysterious woman named Delilah, whose story, along with Daud's, will continue in the upcoming final add-on, The Brigmore Witches.

The Knife of Dunwall releases globally for the Xbox 360, PC and PlayStation 3 on April 16 for $9.99 or 800 Microsoft points.
